During blood sampling, inner sleeve 2 head is also aimed at human blood collection position by hand-held trocar sheath 1, the point-like projection on inner sleeve 2 top first with contact skin, then the press type tail-hood 10 of hemostix rear end is pressed, along with the relative trocar sheath 1 of press type tail-hood 10 moves axially, the first inclined-plane 11 on first acting surface contacts cooperation and forces elastic arm 7 to produce radial direction to step down and swing with the second inclined-plane 12 on the second acting surface, thus drives dynamic salient point 5 to extend out as radial direction relative to needle outlet 3 center to move.When pointing relieving press type tail-hood 10, elastic arm 7 can be kept in the center again.Dynamically salient point 5 also can produce radial direction and moves back and forth in this process, produces dynamically paralysis and stimulation, to shift the attention of people, alleviate the pain that needle body thrusts human body skin to blood sampling point skin around.The Be very effective that the dynamic salient point of this utility model alleviates pain compared with traditional static salient point strengthens.
Embodiment 2: a kind of afterbody press type hemostix dynamic salient point paralysis device
As shown in Fig. 5-Fig. 6, the present embodiment is compared with embodiment 1, and difference is: the front end of described pressing type tail-hood 10 is provided with tubular body, and the inner edge of this tubular body is as the first acting surface, and the second acting surface is located in the circumferential outer rim of the corresponding inner sleeve of each elastic arm 72.Described concaveconvex structure is wedge shaped projection 8, and this wedge shaped projection 8 is located on elastic arm 7 lateral surface.
During blood sampling, inner sleeve 2 head is also aimed at human blood collection position by hand-held trocar sheath 1, the point-like projection on inner sleeve 2 top first with contact skin, then the press type tail-hood 10 of hemostix rear end is pressed, first acting surface contacts with the second acting surface and coordinates, the tubular body inner edge of pressing type tail-hood 10 contacts with the wedge shaped projection 8 on outside elastic arm 7, forces elastic arm 7 to produce radial direction and to step down swing, thus drives dynamic salient point 5 to inside contract as radial direction relative to needle outlet 3 center to move.When pointing relieving press type tail-hood 10, elastic arm 7 can be kept in the center again.Other structures are identical with embodiment 1, here no longer repeated description.
Be explained as follows for performance of the present utility model below:
1. in this utility model, trocar sheath 1 cross section can be square, also can be circular, or other shapes.Trocar sheath also can be named other titles such as shell or housing.Inner sleeve cross section can be square, also can be circular, or other shapes.Pressing type tail-hood 10 not necessarily tubular body can be other versions, as long as its function is one launch button, and can touch dynamic salient point 5 simultaneously.
2., in this utility model, groove 6 quantity that inner sleeve 2 is offered vertically is unrestricted, the amount doesn't matter, specifically can grasp according to actual needs, and also need to consider technologic exploitativeness, these all those skilled in the art will know that.
3. in this utility model, each bar groove 6 can be that interval is uniformly distributed in inner sleeve 2 circumference, also can uneven distribution, but is uniformly distributed as preferred plan.This is that those skilled in the art easily expect.
4. in this utility model, can arrange on each elastic arm 7 about dynamic salient point 5, also can arrange at interval on elastic arm 7.These changes are that those skilled in the art easily expect.
5. in example 2, described each elastic arm 7 with the end face of contact human skin on be equipped with dynamic salient point 5, the corresponding each elastic arm 7 of wedge shaped projection 8 is arranged, and each wedge shaped projection 8 is positioned in same transverse location in inner sleeve 2 central axial direction.But in order to improve action effect further, relative for each wedge shaped projection 8 inner sleeve 2 central axis can be distributed or other distribution forms in the shape of a spiral, being such as interspersed vertically.
6. in example 2, described concaveconvex structure is wedge shaped projection 8, and this wedge shaped projection 8 is located on elastic arm 7 lateral surface.Also can change concaveconvex structure into curved surface, such as this curved design be become undaform projection, this undaform projection is located on elastic arm 7 lateral surface.To being provided with projection by curved surface on the tubular body inner edge of pressing type tail-hood 10, when inner sleeve 2 moves axially press type tail-hood 10 relatively, projection acts on undaform projection and forces elastic arm 7 to produce radial direction back and forth to step down swing, thus drives dynamic salient point 5 relatively to move back and forth as radial direction at needle outlet 3 center.
7. in embodiment 1, if change the direction on the first inclined-plane 11 and the second inclined-plane 12, can make
Dynamic salient point 5 inside contracts as radial direction relative to needle outlet 3 center and moves.This is that those skilled in the art can imagine.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to this utility model spirit change or modify, and all should be encompassed within protection domain of the present utility model.
